[0019] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0020] The following is in conjunction with the appendix Figure 1-2 The present invention will be described in further detail below.

[0021] This utility model discloses a clamping and rotating cabbage harvesting machine.

[0022] Reference Figures 1-2 A clamping and gripping cabbage harvester includes a mounting frame 2, a rotating mechanism, and a multi-claw gripping mechanism. The rotating mechanism is mounted on the mounting frame 2. The multi-claw gripping mechanism has a rotating disk 4 and gripping claws 9 arranged circumferentially along the rotating disk 4. The gripping claws 9 can be manipulated to rotate, causing them to contract or expand. The rotating mechanism can drive the rotating disk 4 to rotate. The device is small in size and can be used for operations on irregular terrain. Compared with traditional harvesting methods, the harvesting method that combines clamping and gripping through the clamping of the gripping claws 9 and the rotation of the rotating disk 4 can maximize the integrity of the cabbage, reduce crop loss, and improve labor efficiency.

[0023] A support frame 6 is provided on the rotating disk 4, and the gripping claw 9 is rotatably fitted on the support frame 6. The multi-claw gripping mechanism also includes a gripping chuck 8. The rotating mechanism can drive the gripping chuck 8 to move axially along the mounting frame 2. A connecting rod 7 rotatably connected to the gripping claw 9 is provided on the gripping chuck 8. The gripping chuck 8 can be manipulated to move axially along the mounting frame 2, causing the gripping claw 9 to contract or expand. The rotating mechanism includes a drive source 11 and a lead screw 10. The drive source 11 is used to drive the lead screw 10 to rotate, and the lead screw 10 is threadedly connected to the gripping chuck 8. In this embodiment, the drive source 11 is a geared motor. A push rod 1 is provided on the mounting frame 2, and the push rod 1 is slidably fitted on the mounting frame 2 in the vertical direction. The rotating disk 4 is loosely fitted at the bottom of the push rod 1, and the drive source 11 is loosely fitted at the bottom of the rotating disk 4. By driving the rotating disk 4 to move axially along the mounting frame 2 through the push rod 1, the axial position of the mounting frame 2 of the multi-claw gripping mechanism is adjusted, realizing the picking and putting down of the cabbage. The rotating disk 4 is loosely fitted at the bottom of the push rod 1 so that the rotating disk 4 will not drive the push rod 1 to rotate synchronously during rotation. The drive source 11 is loosely fitted at the bottom of the rotating disk 4 so that the rotating disk 4 will not drive the drive source 11 to rotate synchronously during rotation.

[0024] The gripping claw 9 has a gripping rod and a gripping part disposed on the gripping rod. The gripping rod is fitted to the support frame 6 and rotatably connected to the connecting rod 7. The gripping part is bucket-shaped and used to grip the cabbage. Three gripping claws 9 are arranged circumferentially along the rotating disk 4. This invention converts the linear motion of the lead screw 10 into the clamping or releasing action of the three gripping claws 9. Specifically, the lead screw 10 is threadedly connected to the gripping chuck 8. When the lead screw 10 rotates, the connecting rod 7 moves along the axial direction of the lead screw 10, thereby pushing the gripping chuck 8 to rotate. The rotation of the gripping chuck 8 drives the gripping claws 9 to move inward or outward, thereby clamping or releasing the cabbage, which has high precision, high reliability and long service life. The lead screw 10 drive can accurately control the position, while the gripping claws 9 can stably grip the cabbage. In addition, since the lead screw 10 drive can withstand large loads and torques, this mechanism is also suitable for heavy-duty and high-speed applications.

[0025] The screw 10 drives the gripping chuck 8 to move downward, which in turn drives the gripping claw 9 to move outward. The screw 10 drives the gripping chuck 8 to move upward, which in turn drives the gripping claw 9 to move inward. At the same time, the gripping claw 9 can drive the rotating disk 4 to rotate synchronously, so that the clamping and gripping are synchronized, thus achieving the purpose of picking cabbage.

[0026] The mounting frame 2 is provided with a moving component 3, which has a moving part for moving the mounting frame 2. In this embodiment, the moving component 3 includes casters, which are located at the bottom of the mounting frame 2 for moving the mounting frame 2, thus facilitating the movement of the harvesting machine.

[0027] The support frame 6 has multiple mounting parts 5 arranged along the axial direction of the mounting frame 2. The gripping claw 9 can be set in the mounting parts 5 at different positions to adjust the axial position of the gripping claw 9 along the mounting frame 2. Specifically, the mounting part 5 includes multiple mounting holes formed in the support frame 6 along the axial direction of the mounting frame 2 and fasteners fixed in the mounting holes. The fasteners can be bolts. The gripping claw 9 is installed in the mounting holes at different positions through the fasteners. By adjusting the position of the gripping claw 9 along the axial direction of the mounting frame 2, since the shape and size of cabbages may vary, the multi-claw gripping mechanism can adjust the position and angle of each claw through the above structure to adapt to cabbages of different sizes. This flexibility ensures that the gripping mechanism can effectively grip cabbages regardless of their size.

[0028] When gripping cabbage, the multi-claw gripping mechanism has multiple gripping claws 9 working together to form a stable support structure. This design can prevent the cabbage from slipping or deforming during gripping and moving, ensuring the stability and reliability of the gripping process.

[0029] The required motor torque for drive source 11 is 9549 * motor power / motor speed. For example, if the motor power is 25.2W and the motor speed is 37 revolutions per minute, the motor torque is 65 kg·cm. However, field tests show that the minimum torque required to break the root of a cabbage is about 50 kg·cm. Exceeding this torque is sufficient to break the cabbage.

[0030] A pressure sensor is installed on the gripping claw 9, located in the gripping section. The pressure sensor detects the pressure between the surface of the gripping claw 9 and the object being gripped, effectively preventing the cabbage from being gripped too tightly by the gripping chuck 8 mechanism, thus preventing damage and improving the integrity of the harvested cabbage. This ensures that the three-claw gripping mechanism controls the gripping force within a suitable pressure range during the gripping process, avoiding unnecessary damage to the cabbage. The pressure sensor has a preset pressure threshold. When the detected pressure value exceeds this threshold or reaches the threshold's critical point, the drive source 11 stops rotating, indicating that the cabbage has been gripped firmly, thus preventing excessive gripping and damage.

[0031] In this embodiment, the clamping and gripping cabbage harvester also includes a control mechanism, which comprises a microcontroller and an electric drive module. The microcontroller, model STC12C5A60S2, is selected as the main control chip, featuring an enhanced 8051 CPU with 1T clock speed, single clock / machine cycle operation, and instruction code fully compatible with the traditional 8051. The electric drive module uses an L298N dual-channel motor drive module to drive the geared motor and achieve forward and reverse rotation.

[0032] The mounting bracket 2 is equipped with a power supply, which is a lithium battery. The lithium battery is used to power the electrical equipment on the harvester, including but not limited to the control mechanism and the drive source 11.
